Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a compression device for a container containing a radioactive substance.

In order to store a predetermined radioactive material in a nuclear power plant, first, the radioactive material is collected in a barrel-shaped container and temporarily stored. In order to minimize the storage volume required for storage, the container filled with radioactive material is compressed and, after compression, put again in another storage container, subsequently closing this storage container and finally storing it finally . In this method, it is important that the compression of the container and the subsequent loading of the compressed container take place very quickly in order to minimize the emission of radiation. Such compression and transshipment of radioactive material occur not only routinely in nuclear power plants, but only at specific times, and the necessary equipment, especially the press equipment, is extremely expensive, so such compression equipment Must be made at least partially transportable. Due to the high compression force of about 4000 tons required for container compression, conventional presses, usually composed of four guide pillars, have a large total height and can only be transported when the press is disassembled . This takes a lot of time,
Costly.

It is therefore an object of the present invention to provide a device for compressing containers containing radioactive substances, which can be transported quickly and easily between two places of use.

This problem is solved by the features of claim 1.
The modular construction with a shielded storage container for the container, a high-pressure press and a loading device for loading the compressed container into the storage container allows for quick assembly and dismantling of the compression device according to the invention. Since at least the high-pressure press is formed as a movable shrinkable unit,
The entire compression device can be transported to metal without significant expenditure or disassembly from one use location to another without significant expense.

The function of the compression device according to the invention is greatly improved if a pre-press is provided between the storage container and the high-pressure press, which pre-compresses the container in a compression direction transverse to the compression direction of the high-pressure press. Since this pre-compression reduces the cross-sectional dimensions of the container, for example the diameter of the barrel, before the actual compression operation, the presses exiting the high-pressure press are stored on the basis of the reduced cross-section, in the same way as the original shaped container. Can be loaded in containers. Moreover, this saves costs because the storage container is the same as the original container for the radioactive material, and therefore does not require extra inventory for the storage container.

Particularly suitable for use in the compression device according to the invention are the lower mold receiving the goods to be compressed, the upper mold and the lower mold capable of entering the compression position in the lower mold from the standby position. Having a cylinder of a piston-cylinder device, the cylinder is formed in a frame movable between a use position and a transport position, the frame is fixed to a guide pillar in a use position, and a piston accommodated in the cylinder in a transport position. This is a high-pressure press that contacts the upper mold that has entered the lower mold.
The high-pressure press can be retracted without any major assembly work, since the high-pressure press can be brought into the transport position in which all moving parts are supported by the base plate, simply by releasing the fixing of the frame to the guide pillars. .

If the high-pressure press is provided with an auxiliary device formed to return the lower die from the operating position to the loading position, the auxiliary device is a frame drive for moving the frame between the transport position and the use position. You can also do In this way, the auxiliary device for moving the lower mold during the pressing operation is led to the secondary use used when the high-pressure press contracts. This saves total volume and reduces the cost of such high pressure presses.

In a preferred embodiment of the high-pressure press, at least one further piston-cylinder arrangement is provided in the piston-cylinder arrangement, the cylinder being formed in the piston of the first piston-cylinder arrangement, the piston being formed by a frame. And the longitudinal axis of another piston-cylinder device is parallel to or coincides with the longitudinal axis of the first piston-cylinder device. This alternative piston-cylinder arrangement has a necessarily smaller diameter than the first piston-cylinder arrangement which produces the main pressure and is used to initiate the rapid movement or advance of the high-pressure press. Because this alternative piston-cylinder device has a small diameter and thus a small cylinder volume, after introducing the hydraulic fluid, up to the point where the force exerted by the other piston-cylinder device can no longer generate the necessary compression force. A large, fast movement of the large piston of the first piston cylinder device is performed. However, at this point, the first piston cylinder device, which increases with the movement of the first piston cylinder device,
Since the cylinder volume of the piston cylinder device is filled with the hydraulic fluid by the suction action, in order to start the original press work by the large piston of the first piston cylinder device, the working fluid is even pressurized by the hydraulic pump. do it. This cascading function of the two piston-cylinder arrangements significantly speeds up the pressing operation. This is advantageous for the treatment of radioactive materials.

A jacket movable along the guiding device is provided for the high-pressure press, which, in the retracted position, generally blocks radiation and closes the high-pressure press in the retracted position, and mounts the high-pressure press in the exit position. The possibility of mobile use of the high-pressure press is further enhanced if the entry and movement are performed.

In that case, it is expedient if a storage and supply device for the hydraulic fluid which exerts a pressure on the piston-cylinder device is provided inside the outer cover. This structure can be used very quickly after transporting the high-pressure press to the point of use. This is because it is only necessary to connect the entire device to the energy supply at the position where the jacket has escaped. The internal hydraulic connection is already operational.
In addition, since the hydraulic fluid storage device is disposed in the casing that has moved upward, the first piston cylinder device operates to fill its cylinder chamber with another piston cylinder device when the piston moves. Since the gravity of the liquid is used, the pressing operation can be further accelerated.

It is also advantageous if a gripper device is provided for supplying and discharging the articles to be compressed to and from the high-pressure press. Integrating the gripper device into the unit of the high-pressure press further increases the compactness of the entire structure, speeds up and moves the goods.

If a shield, preferably formed in the form of a bellows, is provided between the lower mold and the upper mold, when the container is compressed, for example, the container will rupture and the released radioactivity cannot be scattered outside, so that the bellows may not be scattered. Staying inside gives you more radiation protection. In this case, it is preferable to connect the bellows to a suction device for the air loaded with radioactivity and to send this air to the filter device via the suction device.

The aforementioned high-pressure press is not only for use in a compression device according to the invention for containers containing radioactive materials, but also
In principle, it can be employed in all other applications where deploying a high pressure press in various locations is problematic.
Alternatively, a high-pressure press can be used by leaving it stationary.

In a preferred embodiment of the compression device according to the invention, a storage container is provided which has a housing, preferably shielded against radiation, and in which a transport device for the container containing the radioactive substance is provided. ing. A transport device is configured to transport the container from a closable inlet to a closable outlet. This storage container, which can also be made mobile, can be installed alongside a high-pressure press and have a plurality of inlets or outlets.
The container containing the radioactive material to be compressed is stored intermediately in a special place at the nuclear power plant and then transported by shortest route to the storage container, where it stands by for protection by radiation-protected high-pressure presses. I do. The container is then moved to the outlet of the storage container, preferably closest to the gripper device of the high-pressure press, from which it reaches the gripping area of the gripper device. In the storage container of the container to be compressed, this intermediate storage contributes to speeding up the entire compression operation. Because the containers to be compressed can be sent directly from the pre-filled storage container to the high pressure press, there is no longer a long transport path between the intermediate storage and the high pressure press in the power plant.

This spare container can in principle also be used independently of the compression device according to the invention.

A preferred loading device for the compression device according to the invention comprises a lifting and transport device with at least one gripper. The gripper is guided vertically in a generally cylindrical shielding jacket which is connected to the lifting and transporting device in a substantially non-swingable manner. The gripper can enter the storage container to lower the compressed container. This lifting / transporting device, which comprises, for example, an overhead crane, has the advantage that the gripper is guided, so that it is relatively immobile and does not swing during movement. Thus, the pressed product exiting the high-pressure press is directly gripped by the preferably annularly formed gripper, without having to wait for the gripper to stop oscillating. This speeds up the entire work process and reduces the time that radioactive material is not shielded. This shielding jacket can also be connected to a suction facility if necessary.

In this case, it is advantageous if the gripper is formed in an annular shape and surrounds at least one compressed container in a jacket-like manner, the annular shielding being provided on the upper side coaxially with the annular gripper. . Moreover, this arrangement reduces the emission of radiation when the pressed article is transported from the high pressure press to the final storage container. In principle, this loading device can also be used independently of the compression device according to the invention.

If the compression device according to the invention comprises a pre-press, it is preferred to use a pre-press having two opposed cylinders with pre-press rams which are movable in opposition. The compression surfaces of the pre-press rams each have a groove-shaped die cavity with a parabolic cross section, and the longitudinal extension of the die cavities is substantially perpendicular to the different directions of the two pre-press rams. Preferably, the inner dimension between the die cavities measured in the direction of movement with the forming ram abutting is smaller than the width of the die cavity in the open area of the separated prepress ram. By means of this prepress, which is preferably arranged between the storage container and the high-pressure press, the container to be compressed, for example a keg, can first be compressed in a first radial direction, whereby the cross section of the container is reduced. In order to avoid a change in barrel length, the lid side and the bottom side of the barrel are supported during the precompression process. This cross-section reduction allows the pressed product, which has been compressed by a high-pressure press while maintaining this reduced cross-section, to be inserted into a storage container of the same type as the original container containing the radioactive material. This not only simplifies inventory holding, but also provides a single container for radioactive waste. This singulation makes it possible in particular to use the same means of transport for the transport of uncompressed radioactive material and for the transport of already compressed radioactive material.

If the cylinders of this pre-press are separated from each other so that the articles to be pre-compressed can pass through the pre-press across the direction of movement of the pre-press forming ram during the transfer operation, the pre-press can be separated from the storage container and the high-pressure press. The entire press operation can be accelerated since it can be inserted without problems into the transport path between them.

This prepress can in principle also be used outside the compression device according to the invention.

Next, the present invention will be described in detail based on an example with reference to the drawings. 1 is an overall plan view of a compression device according to the present invention, FIG. 2 is a vertical sectional view of a high-pressure press, FIG. 3 is a plan view of a high-pressure press equipped with a gripper, and FIG.

Indicates a pre-press abutted.

FIG. 1 shows the modular construction of a compression device according to the invention for a container containing radioactive material. A number of containers 5 for storing radioactive substances are stored in a modular storage container 2. The storage container 2 loads the container 5 through a plurality of inlets 20 and a plurality of outlets 21.
Can be dropped off.

At one of the outlets 21 there is arranged a pre-press 4, which is constructed in a modular manner, from which the container 5 can be discharged from the storage container via a roller conveyor 22. The gripper device 10 of the high-pressure press 1 enters the pre-press 4 from the side opposite to the roller conveyor 22 of the pre-press, takes out the pre-compressed container 5 and sends it to the high-pressure press 1. The container 5 'compressed by the high-pressure press is subsequently removed from the high-pressure press by the gripper device 10 and lowered onto the roller conveyor 30 of the loading device 3. Subsequently, the lifting / transporting device 31 takes out the compressed container and loads it into the storage container.

The modular construction shown in FIG. 1 of the compression device with juxtaposed modules allows a short, preferably straight path of the container to be compressed from the storage container 2 to a storage container arranged in the area of the loading device 3. .

FIG. 2 shows a vertical sectional view of a high-pressure press configured in a modular manner. Two vertical guide pillars 14 and 1 on base plate 11
4 'is fixed and used to support the compressive force. A frame 15 for accommodating the first piston cylinder device 16 and the second piston cylinder device 17 is fixed to the upper ends of the guide pillars 14, 14 '. Between the frame 15 and the base plate 11, the lower die 12 adjacent to the base plate 11 and the upper die 13 adjacent to the frame 15 are supported by guide pillars 14 and 14 ′ so that they can move vertically independently of each other. I have. Between the lower mold 12 and the upper mold 13 is disposed a preferably bellow-shaped, generally cylindrical shield 18.

In the illustration of FIG. 2, the lower die 12 is lowered to a lower position where the center of the lower die contacts the base plate 11. The central part 120 of the lower mold 12 is formed in a vertical cylindrical shape and is used for receiving the container 5 to be compressed, into which the punch part 130 of the upper mold 13 can enter like a piston.

The frame 15 fixed to the upper ends of the guide pillars 14 and 14 'is guided by flange-shaped arm portions 151 and 152, respectively.
Surround 14, 14 '. Flanged arm parts 151, 152
In the meantime, the dome-shaped central portion 115 of the frame 15 extends, and its upper end projects above the height of the guide pillars 14, 14 '.

In the dome-shaped central portion 150 of the frame 15, a blind hole-shaped cylinder hole 153 opened to the upper mold 13 side is provided.
The piston 160 of the first piston cylinder device 16 is accommodated in the blind hole-shaped cylinder hole 153 so as to be vertically movable. The lower end surface 161 facing the upper mold 13 of the piston 160 contacts the upper end surface of the upper mold 13 and is connected to the upper mold,
It is preferably screwed. Piston 160 and upper die 13
In this assembly type structure, contamination caused by escape of radioactive material from the container 5 to be compressed captures only the upper mold 13 and the piston
160 has the advantage of being protected against such contamination.

The piston 160 has a blind hole-shaped cylinder hole 163 which is open at the center upper side, that is, on the side remote from the upper mold 13.
The piston 170 is movable in the cylinder bore 163 relative to the piston 160 in the axial direction of the first piston cylinder device 16, and the first piston cylinder device 16 and the second piston cylinder device 17 are coaxially arranged. Have been. piston
170 is fixed to a central portion 150 of the frame 15 by a piston rod 171 and is supported by the central portion 150 in the axial direction.

Hydraulic fluid can be pumped into the gap between the lower end face 172 of the piston 170 opposite the center 150 and the piston 160, for example, via a fluid supply passage through a piston rod 171. Similarly, the working fluid can be introduced into a gap between the upper end face 162 of the piston 60 facing the center 150 of the frame 15 and the frame 15. The function of the two piston cylinder devices 16, 17 will be described later.

The area of the flange-like arm portions 151, 152 of the frame 15 is fixed to the guide pillars 14, 14 'as described below. Since the fixing of the area of the arm part 152 is formed in the same manner, only the fixing of the arm part 151 will be described.

A vertical hole 154 extends through the flanged arm portion 151. Since the hole diameter substantially corresponds to the outer shape of the guide pillar 14, the frame 15 can move up and down on the guide pillar 14. The upper area of the bore 154, i.e., opposite the base plate 11, forms a portion 154 'having an enlarged diameter, and the intermediate portion between the bore 154 and the expanded portion 154' forms an annular stop 154 ".

The guide pillar 14 is provided with a circumferential groove 140 in the upper end area, in which a support ring 141, preferably consisting of two half bodies, can be inserted. In this case, the outer diameter of the support ring 141 is larger than the outer diameter of the guide pillar 14, and roughly corresponds to the inner diameter of the expanded portion 154 'of the hole 154. The cover 14 rests on the upper free end of the guide pillar 14 and the lower axial annular flange 142 ′ forms a gap or hole 154 between the flanged arm portion 151 of the frame 15 and the outer periphery of the guide pillar 14. It enters the extension 154 'and is thus centered. An annular flange 142 "projecting radially beyond the axial annular flange 142 'is secured to the flanged arm portion 151 with screws 143.

In this way, the frame is fixed to the guide pillar 14 between the support ring 141, which contacts the stop 154 "of the hole 154, and the cover 142, which is supported on the upper free end 144 of the guide pillar 14. While supporting the weight of frame 15,
The support ring 141 supports the compressive force received by the frame 15 on the guide pillar.

FIG. 3 shows a plan view of the high-pressure press 1. High pressure press 2
It can be seen that the line connecting the centers of the guide pillars 14, 14 'of the book is arranged at an angle .alpha. Of preferably about 45 DEG with respect to the transport line Z through which the container 5 to be compressed passes. . This minimizes the width of the module of the high-pressure press 1, so that the transport path of the container to be compressed and therefore the transport time can also be minimized. This is particularly advantageous in terms of reducing radiation exposure during the treatment of radioactive materials. At the same time, this angular arrangement makes it possible for the gripper insert 10 described below to enter the press chamber of the high-pressure press 1 without problems.

FIG. 3 also shows the gripper device 10 assigned to the high-pressure press 1 and mounted in the high-pressure press module.
The gripper device 10 can pivot about a vertical axis parallel to the axis X of the high pressure press. The gripper device 10 is equipped with gripper fingers 100 and 101 as is well known, and can receive the container 5 to be compressed from the inlet side A of the high-pressure press module and insert it into the press chamber below the upper die 13 of the high-pressure press. It is designed so that it can be removed therefrom after the pressing operation and lowered onto the roller conveyor 30 at the outlet side B of the high-pressure press module.

Also, in FIG. 3, it is arranged vertically and the lower end is preferably a frame 15
Alternatively, two auxiliary devices 19, 19 'supported by the plate 11 and whose upper end is attached to the lower mold 12 are recognized. Auxiliary device 19, 19 '
Is driven to extend vertically or in the compression direction to move the lower mold 12 from the lowest position to the upper position shown in FIG. 5A. At the same time, the auxiliary devices 19, 19 'support the frame 15 which is not fixed to the guide pillars 14, 14' in the transport position and, as will be explained below, the use position shown in FIG. Used to move up and down between.

FIG. 4 shows a side view of the module of the high-pressure press 1, in which the vertically movable cover-like jacket 110 has been moved upward on the base plate. A hydraulic fluid storage tank 111 is provided in the outer casing, and the high-pressure press 1 is connected via a communication hose (not shown).
Is linked to Inside the jacket 110, as a shield against radiation, a variable modular member can be provided which can remain as regional radiation protection after the removal of the jacket 110.

5A, 5B, 5C and 5D show the high-pressure press 1 in four different operating states. 5A shows the charging position of the high-pressure press 1, FIG. 5B shows the position of the high-pressure press 1 immediately before the start of the compression operation, and FIG.
Is a high-pressure press at the time of compression operation where compression is approximately the maximum.
FIG. 5D shows the transport position where the high-pressure press is contracted. Next, the operation of the high-pressure press will be described with reference to FIGS. 5A to 5D.

FIG. 5A shows the high-pressure press 1 in the loading position. In this position, both the first piston-cylinder device 16 and the second piston-cylinder device 17 are completely retracted. That is, each piston is entirely within its associated cylinder. The upper die 13 is a separate piston-cylinder device 17 arranged on a piston 170.
The upper cylinder chamber 173 holds the upper position. The lower mold 12 is moved to the upper position by the associated auxiliary devices 19, 19 ', where it contacts the upper mold 13 and the punch part
130 enters cylindrical hole 121 of central portion 120 of lower mold 12. In this way, the gap between the lower mold 12 and the base plate 11 can be freely reached, so that the gripper device 10 can lower the container 5 to be compressed onto the base plate below the punch part 130. .

In FIG. 5B, the lower mold 12 has been lowered by the auxiliary devices 19, 19 ', the lower end of which is on the base plate 11, and the lower mold 12 surrounds the container 5 to be compressed. However, the upper mold 13 is still at the upper position. In this arrangement, a bellows-shaped shield 18 is stretched between the lower mold 12 and the upper mold 13.

Therefore, first, the hydraulic fluid is introduced into the lower cylinder chamber 174 below the piston 170 of the second piston cylinder device 17. Since the working cross-section of the second piston-cylinder device 17 is small compared to the first piston-cylinder device 16, the piston 160 of the first piston-cylinder device 16 moves down relatively quickly.

This movement of the piston 160 of the first piston-cylinder device 16 simultaneously moves the upper die 13 down,
130 enters cylindrical hole 121 of central portion 120 of lower mold 12. As a result of the effective movement of the piston 160, the upper end face 162 of the piston 160
In addition, a gradually increasing cylinder chamber is formed on the central portion 150 of the frame 15, and a negative pressure is generated in the hydraulic fluid supply unit connected thereto, so that the hydraulic fluid is sucked from the storage tank 111 into this cylinder chamber. Since the storage tank 111 is arranged higher than the upper central portion 150 of the frame 15, this hydraulic fluid transport is promoted by the gravity of the hydraulic fluid.

As soon as the punch part 130 comes into contact with the container 5 to be compressed, the back pressure increases and the compression force exerted by the second piston-cylinder arrangement 17 is no longer sufficient to continue compressing the container 5. At this moment, the piston 16 and the center of the frame 15
Since the hydraulic fluid sucked into the cylinder chamber of the first piston cylinder device 16 between 150 and 150 is pressurized and another hydraulic fluid is pressurized and introduced, the second piston cylinder device 16
The working surface of the first piston-cylinder device 16 which is much larger than the working surface of 17 works, and the compression operation is performed with a much higher force.
The process is continued until the container 5 reaches the maximum compression state shown in FIG. 5C.

Subsequently, the upper mold 13 is lifted by the hydraulic pressure of the working fluid introduced into the upper cylinder chamber 173.

FIG. 5D shows the contracted position of the high-pressure press 1. In order to reach this state, first, when the lower die 12 is supported on the base plate 11 by the auxiliary devices 19, 19 ', the lower die 12 is placed at a position corresponding to the position shown in FIG. , 19 ', frame 15
5B, the respective covers 142 are removed from the guide pillars 14, 14 'by removing the screws 143 at positions corresponding to the positions shown in FIG. 5B. Next, the cover 142 is removed from the guide pillar, and the frame 15 is moved down together with the upper mold 13 and possibly the lower mold 12 by the auxiliary devices 19, 19 'to be lowered. In that case frame 15
Can follow the downward movement of the upper mold 13 by its own weight or can be moved downward or upward by the auxiliary devices 19, 19 '. If the respective support ring 141 is formed in an assembled manner, then further support rings can be removed. The high pressure press can also be locked in the transport position shown in FIG. 5D for transport. Subsequently, the jacket 110 is lowered and the high-pressure press 1 is closed. In this way, the high-pressure press is contracted for transport into a compact unit. This unit is relatively easy to transport because the total height has been reduced by shrinkage.

FIG. 6 shows the storage container 2. As already detailed, the storage container 2 has a housing that shields against radiation. The housing has at least one closable inlet
It has 20 and at least one closable outlet 21. FIG.
In this embodiment, four closeable inlets 20 and four closeable outlets 21 are provided. Inlets and outlets can also be closed to shield radiation. Roller conveyor 22
Respectively communicate with or emerge from the openings. Inside the storage container, conveying devices, for example, chain conveyors or roller conveyors, are provided longitudinally parallel to one another.
Also provided is at least one transverse transport device 24 which works across the vertical conveyors 23, 23 ', 24 ". In this way it is possible to load the container 5 into the storage container 2 via any opening. Almost all possible locations are occupied by containers 5 by means of a transfer device inside and outside the storage container, and a fast uninterrupted unloading of the container 5 based on the vertical and horizontal conveyors inside the storage container 2. , With which a continuous supply of this container to the high-pressure press can take place.

FIG. 7 shows a front view of the loading device 3. A running rail 33 formed as a cantilever beam is pivotally mounted on the side of the module of the high-pressure press and can be pivoted towards or into the module for transport. The lifting / transporting device 31 is provided so as to be movable along the traveling rail, and is suspended from the traveling rail. The lifting / transporting device 31 has a gripper 34 formed in a substantially annular shape. The gripper 34 comprises two half-cylindrical half-body bodies, which can be brought into radial contact or separated by a drive 35. In this way 2
The half-body can grip the compressed container 5 'and release it again, the container being surrounded by the half-body in the gripped state, so that the half-body is a kind of radiation protection. Can play a role.

An annular and generally cylindrical gripper 34 is disposed inside an upper annular and cylindrical shield jacket 36 and can be guided and moved vertically therein. The shielding jacket 36 is connected to the overhead crane 37 traveling on the traveling rail 33 so as to be substantially non-turnable, that is, does not swing during use. As a result, the lifting / transporting device 31
The movement of the gripper 34 and the lifting and lowering of the gripper 34 suppress the pendulum movement of the gripper 34, so that the gripper can receive the compressed container 5 'very quickly, and the lifting / transporting device as in the case of a conventional crane. There is no need to wait for the shaking to stop. This also significantly reduces the total operating time, thus minimizing radioactive material exposure outside the protected area. By means of the lifting / transporting device thus formed, the compressed container 5 'can be lowered into the storage container, wherein a plurality of compressed containers 5' are uncompressed.
It can be inserted into a storage container of the same size as.

FIGS. 8A and 8B show a prepress 4 having two opposed guides 40, 42. FIG. Prepress rams 41, 43, which are movable oppositely, are arranged in the guides 40, 42 so as to be able to move in the horizontal direction. The pre-press rams 41, 43 are driven by piston cylinder devices 46, 47. The rams 41, 43 of the pre-press have groove-shaped die cavities 44, 45 on the respective opposing compression surfaces. Each grooved die cavity 44, 45 has a radial cross section, and the longitudinal extension of the die cavities 44, 45 is substantially perpendicular to the direction of travel of the two prepress rams, preferably of the high pressure press 1. It runs in the compression direction, that is, vertically in this example. The parabolic cross-sectional views of the die cavities 44, 45 show that the internal method, measured in the direction of movement between the die cavities in the area of the press axis Y of the prepress, is used to determine the respective die cavities 44 in the open area of the separated prepress ram. , Designed to be less than 45 widths. This width is indicated by b in FIG. 8A, and illustrates the above inner method.
This is indicated by a in FIG. 8B. Because of this shape of the radial die cavity, the container 5 with an initial diameter of approximately b is compressed to a smaller diameter a, so that the container further compressed in the vertical direction is later used as an empty container as a pressed product 5 '. 5 can be inserted. To achieve this, each pre-press ram 41, 43 has opposing ends in contact with each other at the maximum approach position shown in FIG. 8B, between which has approximately a diameter a as can be seen in FIG. 8B. Form a cylindrical void. In order to avoid changes in the length of the pre-compressed container, the lid and the bottom area of the container are supported during pre-compression.

A gap is formed between the guides 40 and 42 of the pre-press 4 and a roller conveyor 22 coming from the storage container leads into this gap from one side and from the other side to remove the pre-compressed container 5 The gripper device 10 can enter this gap.

In the above description, the compression device in which the high-pressure press acts in the vertical direction has been described, but the high-pressure press can move in the horizontal direction,
It is also conceivable to configure all devices so that the axis X runs horizontally. In such an embodiment, the lower mold 12 is
A radial opening in which individual articles to be compressed can be put into the press. This opening can then be closed for the pressing operation. For this purpose, the line connecting the central axes of the two guide pillars is preferably arranged at an angle of 45 ° with respect to the horizontal.

Preferably, the modules 1, 2, 3 and 4 of the compression device comprise wheels that can roll on rails.
